Printing press and method for the production of newspapers

Abstract

The printing press for producing newspapers includes several unwinders from which coldset webs can be unreeled, coldset printing couples for printing the coldset webs with coldset inks, coldset formers and a coldset folder for processing the coldset webs into longitudinally and transversely folded coldset signatures. The printing press also includes an additional unwinder from which a heatset web can be unreeled, heatset printing couples for printing the heatset web with heatset inks, a dryer for drying the printed heatset web, a heatset former and a heatset folder for processing the heatset web into a longitudinally and transversely folded heatset signature. Finally, a processing device processes the heatset signature into a magazine.

1 . A printing press for producing newspapers, comprising: 
 at least one unwinder from which at least one coldset web can be unreeled;    coldset printing couples for printing the at least one coldset web with coldset inks;    at least one coldset former and a coldset folder for processing the at least one coldset web into at least one longitudinally and transversely folded coldset signature;    at least one additional unwinder from which at least one heatset web can be unreeled;    heatset printing couples for printing the at least one heatset web with heatset inks;    a dryer for drying the at least one printed heatset web;    at least one heatset former and a heatset folder for processing the at least one heatset web into at least one longitudinally and transversely folded heatset signature; and    a processing device for processing the at least one heatset signature into at least one magazine.    
   
   
       2 . The printing press of  claim 1 , wherein the coldset and heatset printing couples are operatable at a same speed or at a different speed.  
   
   
       3 . The printing press of  claim 1 , wherein the processing device is designed to insert the at least one magazine into one of the at least one coldset signatures.  
   
   
       4 . The printing press of  claim 1 , wherein the printing press has a width of four vertical newspaper pages, and further comprises two coldset formers assigned to the coldset folder for producing first and second coldset signatures, and two heatset formers assigned to the heatset folder for producing two heatset signatures, wherein the processing device is designed to process the two heatset signatures into two magazines and to insert the second coldset signature and the two magazines into the first coldset signature.  
   
   
       5 . The printing press of  claim 1 , wherein the coldset printing couples are designed to print the at least one coldset web with vertical broadsheet or horizontal tabloid pages, and the heatset printing couples are designed to print the at least one heatset web with horizontal tabloid pages.  
   
   
       6 . The printing press of  claim 1 , further comprising two coldset formers assigned to the coldset folder for producing first and second coldset signatures with numbers of pages different from each other, wherein at least one of the two coldset formers is designed to guide partial webs.  
   
   
       7 . The printing press of  claim 1 , further comprising two coldset formers assigned to the coldset folder for producing first and second coldset signatures with numbers of pages different from each other, wherein the two coldset formers are designed to form web strands of the coldset webs and to guide at least one web strand leaving one of the two coldset formers to at least one web strand leaving the other one of the coldset formers before the web strands enter the coldset folder.  
   
   
       8 . The printing press of  claim 1 , further comprising two coldset formers assigned to the coldset folder for producing first and second coldset signatures with numbers of pages different from each other, a cutting device for cutting the coldset web into web strands, and angle bars to lay the web strands on top of each other.  
   
   
       9 . A process for producing newspapers with a printing press, comprising the steps of: 
 printing, in the printing press, at least one coldset web with coldset inks and producing at least one longitudinally and transversely folded coldset signature from the at least one coldset web;    printing, in the printing press, at least one heatset web with heatset inks, drying the at least one printed heatset web, and producing at least one longitudinally and transversely folded heatset signature from the at least one heatset web, wherein said steps of printing at least one heatset web, drying the at least one printed heatset web and producing the at least one heatset signature are performed at the same time as said steps of printing at least one coldest web and producing the at least one coldset signature; and    processing the at least one heatset signature into at least one magazine.    
   
   
       10 . The process of  claim 9 , wherein the steps of printing the at least one coldset and heatset webs comprise the step of moving the at least one coldset and heatset webs at a same speed or at a different speed.  
   
   
       11 . The process of  claim 9 , further comprising the step of inserting the at least one magazine into the at least one coldset signature.  
   
   
       12 . The process of  claim 9 , wherein the step of producing the at least one coldset signature comprises producing first and second coldset signatures, the step of producing the at least one heatset signature comprises producing two heatset signatures, and the step of processing the at least one heatset signature into at least one magazine comprises processing the two heatset signatures into two magazines, the method further comprising the steps of inserting the second coldset signature into the first coldset signature, and inserting the two magazines into the first coldset signature.
